TOR Rectifier
HEXFREDTM
Features
. Reduced RFI and EMI
. Reduced Snubbing
. Extensive Characterization of
Recovery Parameters
Description
HEXFREDWdiodes are optimized to reduce losses and EMI/RFI in high frequency
power conditioning systems. An extensive characterization of the recovery
behavior for different values of current, temperature and di/dt simplifies the
calculations of losses in the operating conditions. The softness ofthe recovery
eliminates the need for a snubber in most applications. These devices are
ideally suited for power converters, motors drives and other applications where
switching losses are significant portion of the total losses.
